To rtZZ whom it mag concern.-

Be it known that we, FRANK W. KINNEY and RAYMOND B. PRICE, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Bringing the Ends of Rubber Tires Together; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates toa novel construction in a device for bringing the ends of solid rubber vehicle-tires together after same have been mounted in therim, the object being to provide a simple and efficient device of this character; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating our invention, Figure 1 is a front elevation of a device constructed in accordance with our invention. Fig. 2 is a side elevation of same. Fig. 3 is a front elevation of a modified form of construction.

Our invention, broadly stated, consists in a device upon which the wheel containing the newly-mounted tire is adapted to be revolubly mounted and in providing a roller carried by movable levers which bears upon the tire and is revolved thereby. The roller is brought to bear upon the tire at one point and the wheel is then partially revolved, so that theroller cbmpresses the rubber toward one end of the tire, thereby forcing said end toward theother.

end of the tire, and thus rapidly bringing said ends together. Very numerous devices for this purpose may be designed, but we have illustrated only two of same, these being deemed sufficient for purposes of illustration.

In said drawings, A indicates a frame comprising two parallel standards connected at their upper and lower ends by means of crosspieces. I Said standards are provided about midway between their ends with perforations or similar devices B to receive a pin or shaft C, upon which a wheel D may be mounted. A shaft E is journaled in bearings in the upper end portion of said frame A and between its ends carries a sleeve F, having two parallel arms,in the ends of which the shaft Gofaroller H is journaled. At one end said shaft E car ries a crank-arm I, which is partially offset outwardlyat its free end. Movably mounted on said shaft E adjacent said crank-arm I is a lever J, which depends therefrom and at its lower end carries a pivoted rack K, adapted to engage a projection L on one of said standards. One end of said rack-is bent to form a grip M, which when pressed against said lever J throws said rack out of engagement with said projection L. A tension-spring N is interposed between the end. of the crank-arm I and an adjacentpoint in said lever J, so that by pulling said lever outwardly tension is applied to said crank-arm I,'which turns said shaft E and forces said roller H down, so as to bear upon the tire of the wheel. Said roller H is preferably always so mounted as to swing in the plane of the wheel upon which it operates, as this obviates the necessity of accurate adjustment of the pin or shaft C.

In mounting rubber tires on wheels by means of fastening-bands passing longitudi- .nally through the tire the ends of the tire are compressed back from the end portions of the fastening-band, so asto leave the latter free to be secured together. The ends of the band are drawn together by means of tension devices, and after being secured the ends of the tire remain separated and must be brought together. The compression of the rubber may extend either entirely or only partially around the Wheel, and by bringing the roller H to gins and turning the Wheel the roller forces the ends of the tire toward each other until they are in contact, thus covering the joint in the fastening-band.

' In Fig. 3.we have shown another .formof our device, in which a single standard 0 is employed, having perforations to receive the pin C to support the wheel. The said standard 5 bear upon the point where compression becarries a face-plate Pat its upperend, which 5 is provided with a projecting pin Q, on which a bell-crank lever R is pivoted. The said bell-crank lever R carries the roller II at one end and at its other end is bifurcated to receive the free end of a rod S, pivotally secured at one end to the short arm of a bellcrank lever T, pivoted at its elbow to a pin on said face-plate. Said rod S carries a-collar U at its free end, between which and said lever B a compression-spring V is interposed. By drawing the free end of said lever T downwardly said spring Vis compressed and forces the roller down upon the tire in an obvious manner. Said lever T may be secured in any desired position by means of a collar XV, longitudinally movable thereon and which may be secured against movement by means of the set-screw X. Thcsaid collar \V is carried by the free end of a link Y, pivotally secured at its other end to a pin Z on said faceplate.

\Ve desire it to be understood that we do not limit ourselves to either of the constructions shown and described, as same may be changed and varied without departing from the spirit of our invention.

\Ve claim as our invention 1.
